IMPROVEMENT IN HANKS FOR SAlLS.

Specification forming part of Letters Patent No. 115,712, dated June 6,1871.

showing it open. Fig. 2 is a perspective view,

representing the device attached to a mast and sail; and Fig. 3 is asimilar view, representing it as used in connection with a stay insteadof a mast.

Similar letters of reference indicatey corresponding parts. l

This invention relates to that class ot' hanks or mast-hoops in whichsaid articles are made in two or more parts, hinged or otherwiseconnected together, and capable oi' opening so as to be placed aroundthe mast or stay, and through the eyelet-holes, and then of being closedand fastened to hold the sail; audit consists in an improvedconstruction of said hoops or hanlrs, whereby the operation of openingand closing them is facilitated, and a more effective and convenientdevice is produced at less cost than heretofore.

In the drawing, D D represent the two jaws of the hanlr or hoop,articulated together at U, and having their ends beveled, and whenclosed overlapping each other. The parts D D are bent toward each otherso as to meet at the center, thus forming two loops, one of whichincloses the mast or stay and the otherthe boltrope of the sail. At thepoint where the said parts D D thus come together at the center of thedevice a mortise-and-shoulder, J, is formed on one side, and asnap-catch, A., operated by a spring, B, is attached to the other side,so as to enter the mortise, snap over the shoulder, and hold the twosides of the hoop firmly locked together when closed. To open them it,ot' course, is only necessary to release the catch from the shoulder ofthe mortise and separate the loose ends of the jaws D D.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

The bank or mast-hoop herein described, consisting of the jaws D D,hinged at C, and bent in the forni described, in combination with thespring-catch A B and the mortise-andshoulder J, substantially as and forthe purpose specified.
